tableView的plain樣式的headerView的上拉過程當中懸停解決方法

//去掉UItableview headerview黏性(sticky) 去掉header的浮動效果

- (void)scrollViewDidScroll:(UIScrollView *)scrollView {

    if (scrollView == self.tableView)

    {

        CGFloat sectionHeaderHeight = 100; //sectionHeaderHeight

        if (scrollView.contentOffset.y<=sectionHeaderHeight&&scrollView.contentOffset.y>=0) {

            scrollView.contentInset = UIEdgeInsetsMake(-scrollView.contentOffset.y, 0, 0, 0);

        } else if (scrollView.contentOffset.y>=sectionHeaderHeight) {

            scrollView.contentInset = UIEdgeInsetsMake(-sectionHeaderHeight, 0, 0, 0);

        }

    }

}
